Arcade gave differing accounts of his past life, and as yet there is no evidence to substantiate any of those accounts. Apparently Arcade told falsehoods about his past to mislead and confuse his opponents for his own amusement.
One of Arcade's accounts stated that he was the spoiled son of a millionaire living in Beverley Hills, California, and killed his own father to acquire his vast sums of money on his 21st birthday, possibly also because he had treated him like he was worthless. In killing his father, Arcade discovered that he had a talent and liking for murder. He therefore became an assassin, but was soon bored with killing by ordinary means, and used his great wealth to construct hidden complexes of high-tech death traps designed in the manner of an amusement park.
Powers: Arcade normally has no superpowers of his own, but gained a multitude of energy-based powers via a nanomachine-enhanced suit that only functioned within his new Murderworld in Antarctica.
His insanity seemingly grants him some level of comic awareness, allowing him (for example) to grasp and eat the little angel and demon on Deadpool's shoulders.
Abilities: --Genius Intelligence: Although he has no superhuman powers, Arcade has a genius level I.Q. and a natural aptitude for mechanics, architecture and applied technology. A brilliant and self-taught designer, Arcade applies his talents to the construction of mobile amusement park-like deathtraps, which he calls "Murderworlds".
